2 days ago o/d off led started blinking, but truck still drives fine (98 f150 - 4.6l). had Autozone check for codes yesterday, nothing came up. (code reader probably pretty basic), today got out on the highway o/d led started blinging again and cruise control didn't work. Anyone know how to find out what is going on for sure without going to dealership? (I haven't taken it in yet for recall yet)
After the light has bee flashing there should be codes stored. I wonder if you could get someone with more knowledge and a better scanner to check it for you.
Hopefully it's something as simple as a bad VSS sensor on the rear end.
It's a pretty common part to replace. If you search the forum here you'll probably find more info on it.
